How brightly colored fruits and veggies protect against cancer 

The foods we eat play a significant role in our health. Processed foods often contain additives and are stripped of their nutritive value. Junk foods that contain ingredients like high fructose corn syrup and trans fats promote chronic inflammation and weaken the immune system — factors that allow chronic diseases like cancer to ensue.  

Data show that in 2015 there will be an estimated 1,658,370 new cases of cancer and 589,430 deaths from the disease in the United States. By 2030, cancer, not heart disease, will be the No. 1 killer of Americans. While these facts are grim, it’s also important to understand that this doesn’t have to be the case.

Cancer isn’t smarter; it’s just stealthier. The truth of the matter is that cancer cells lie in our bodies for years waiting for the right conditions for it to grow and spread. How many years? Well, through postmortem studies we know that cancer has been found in the bodies of people in their 20s. So people can be walking around with cancer and don’t even know it until much later in life.

Cancer stem cells remain dormant until the conditions in the body are ideal — preferably when immune system is weak — before it begins to surge. More aggressive forms of cancer cells possess surface markers that render them invisible so they can remain undetected for years. Other cells are even capable of turning off tumor suppressor genes. 

Once cancer cells become active they proliferate. While some cells are benign, other tumors grow and spread to other tissues, a process called metastasis.

To make matters more complex, cancers stem cells may develop resistance to cancer treatments like radiation and chemotherapy.

But we are not defenseless against cancer. Cancer is preventable. In my new book, The Gene Therapy Plan, an entire chapter is dedicated to chemopreventive approaches through diet and lifestyle. In the book, I explain the crucial role that nutritional epigenetics plays in cancer prevention. Epigenetics is the study of chemical tags called epigenes that modify our DNA in ways that activates or inactivates genes to keep us healthy or make us sick.

So nutritional epigenetics is the way in which our diet impacts our health at the level of our DNA. The bioactive compounds found in wholesome foods affect our epigenes to boost health and thwart disease. When it comes to cancer, there’s a wide array of substances found in various foods that squelch cancer cells.

When you walk through a farmers market or supermarket, those brightly colored fruits and veggies get their hues from powerful phytonutrients that possess anti-inflammatory and antioxidant effects that work to prevent cellular damage. Many of those compounds work to inhibit many of the ways in which cancer cells work to proliferate and spread in the body.

Eating a variety of produce daily has been shown to protect against cancer as well as other conditions like heart disease, obesity, and diabetes. Because there is no specific do-it-all nutrient that fights cancer, consume fruits and vegetables with various colors. These phytocompounds work together to kill cancer cells from the onset by enhancing the immune system.

Here are some fruits and vegetables that you need to include in your diet for cancer prevention.  

Apples are packed with vitamin C, fiber, and quercetin. Quercetin, much of which is contained in the peel, is an anti-inflammatory, antioxidant nutrient that helps to fight cancer.

Beets contain betaine a nutrient that block cancer development.

Broccoli and broccoli sprouts contain sulforaphane, a nutrient that inhibits cancer.

Radishes contain anthocyanins and vitamin C — compounds that possess anti-inflammatory and antioxidant compounds that help to prevent cancer.

Sweet potatoes are loaded with fiber. They also contain beta-carotene. Don’t peel off the skin, or you’ll be throwing away thousands of phytochemicals. 

Tomatoes contain lycopene, an anticancer nutrient that promote cancer apoptosis (cell death). Cook whole tomatoes to increase the bioavailability of the healthful nutrients it contains.

Black raspberries are packed with resveratrol, a promoter of cancer cell death.  It also activates hundreds of tumor suppressor genes. Because this fruit isn’t always in season, you can purchase its powdered form too.

Grapes also contain resveratrol. This anti-inflammatory, antioxidant nutrient prevents cancer.

Grapefruit contains loads of vitamin C and detoxifies the body and eliminates cancer-causing substances. 

Watermelon is rich in vitamins A and C and contains more lycopene than fresh tomatoes.

Research Links Mild Cognitive Impairment to Alzheimer’s Disease

Screen Shot 2015-07-27 at 12.22.56 PM

Over 5 million people age 65 and older are living with Alzheimer’s disease — the sixth leading cause of death in the U.S. AD is a neurological condition that is marked by progressive worsening of memory loss and increasing loss of one’s ability to carry out activities of daily living.

The hallmark signs of Alzheimer’s disease are plaques and tangles. Beta-amyloid plaques are deposits of sticky proteins in the brain that clump together and interrupt the communication between neurons (nerve cells). Neurofibrillary tangles are modifications in tau, a brain protein.

These proteins damage microtubules that are responsible for the transportation of material along neuronal extensions called neurites that allow nerve cells to communicate with each other. The more plaques and tangles build up, the more pronounced an individual’s memory and cognitive deficits become.

But not every instance of forgetfulness is indicative of early AD. The brain ages just like every other organ. So as we get older, we may experience problems like remembering where we’ve placed our keys or recalling what a person’s name is. Forgetfulness is a part of getting older and is attributed to the fact that as we age brain size become smaller, inflammation and free radicals damage is increased, blood flow is reduced, and plaques and tangles are formed.

So what’s the difference between changes in the brain of a normal, aging person and someone with AD? Changes like plaques, tangles, and inflammation become worse over time and irreversibly destroy memory and cognition.

Distinguishing between signs of forgetfulness that are normal or are associated with AD have been assessed through tests like the Mini-Mental Status Exam that helps to track memory and cognitive changes in older adults. But researchers have also been exploring new ways to identify AD. Studies show that a type of mild cognitive impairment (MCI) may be a harbinger of AD.

There are many subtypes of MCI. One that has been studied and linked to the development of Alzheimer’s disease is called amnestic mild cognitive impairment (aMCI). Memory loss is the most prominent feature of aMCI. People with aMCI have been shown to progress to AD more than those without aMCI.

In one study, researchers evaluated the brain tissue of people who were diagnosed with aMCI and found that more than 70 percent of those individuals progressed to Alzheimer’s disease.

Data from a different study used MRI to identify atrophy in the hippocampus and entorhinal cortex (temporal lobe structures responsible for making and storing memories) of people with aMCI and healthy brains over a five-year period. Among those with smaller temporal lobe structures, the progression to AD was shorter.

These studies provide useful insights that may help to shape and improve the way in which AD is detected and treated. While there are drugs that are prescribed to treat AD, there is still no cure.

In my new book, The Gene Therapy Plan, I provide information on ways to promote healthy aging, namely through a wholesome diet. To avoid premature aging and to bolster brain health, skip the processed foods and consume plenty of whole foods. By eating whole foods like fruits and vegetables, herbs and spices, the body is able to obtain optimal nutrition to bolster healthy metabolism and produce lots of energy.

Wellness tips to maintain a healthy weight

Has it been a long time since you’ve stepped on a scale and got excited to see how many pounds you weigh? If you answered “yes,” then you struggle with your weight, so the scale is not likely your friend. With millions of Americans struggling with their weight, the nation’s obesity epidemic is a public health crisis.

And it’s a problem that continues to increase in spite of all the physical fitness messages that we are inundated with in our society. We have so many opportunities to lose weight from dietary regimens to planned meals to workout classes. So why aren’t we, as a nation, healthier?

While many people are able to lose weight, keeping the weight off is another matter entirely. If you’re relying on a test of wills to help you lose weight, then you’re setting yourself up for disappointment. Willpower, as it turns out, isn’t the best approach to facilitate weight loss. Because in our junk food packed society, temptations are everywhere.

And data show that relying on willpower as a strategy to attain a healthy weight will undoubtedly set people up to fail. Why? Willpower is reduced over time. Think of it this way, you spend your day making all kinds of decisions: Easy decisions like what to wear to work to more difficult ones that affect our health and finances. With each decision, researchers theorize that we deplete the limited amount of willpower we have as our day moves along. So when we’ve tapped out our willpower reserve, we tend to make poor decisions like snacking on chips, donuts, and candy bars or trading in our workout to lounge on the couch in front of the television.

So if willpower isn’t a reliable strategy for a healthy diet and weight, what is? It’s essential to find what physical activity means to you. Tailor strategies for a healthy lifestyle around things you enjoy. Also, be flexible in the process of achieving a healthy weight because wellness is a lifelong endeavor and what may have worked at one stage in your life may not be cutting in anymore. Here are some healthful tips that you can use to trim down your bulging waistline and achieve a healthier life.

What’s it Worth to You?

When it comes to achieving a healthy weight, shift your focus away from a desired dress or pants size and place your attention on life-improving strategies. Use meaningful goals to fuel your passion for health and fitness to help you achieve a healthy weight. For instance, perhaps you want to feel energized throughout your day or you want to keep up with your children when it’s playtime.

Let’s Get Physical!

Physical activity isn’t the same for everyone. So while your spouse may love running, maybe you enjoy swimming or walking. Take the time to figure out what you like and don’t like. Think long and hard before you invest in a gym membership. Have you signed up for a gym membership only to pay a monthly fee and you rarely make an appearance? If this sounds like you, don’t repeat history. Try something new.

Find Walking Buddies.

While hitting the gym is a time-restricted activity, there are many opportunities to walk throughout your day. Try to identify those times in your day when you can walk. It may be during the lunch hour at work. Ask someone at work if they want to walk with for a couple of minutes during your lunch hour.

Be “Step Wise.”

I know you’d rather take the elevator. It’s faster. If your office or apartment is in a reasonable distance from the ground floor, take the stairs — it’s good cardio!

There are many benefits to engaging in regular physical activity. Shedding those extra pounds helps to keep a healthy weight; lowers the risk of high blood pressure; reduces the risk for chronic disease like type 2 diabetes, heart attack and stroke, and cancer; and improves symptoms of anxiety and depression. And while physical activity helps to curb weight gain, eating a healthful diet is an integral part of living a healthy lifestyle. Watch my healthy weight video for tips on foods that prevent weight gain.

The Diabetes-Alzheimer’s Disease Link

Brain Buster and Booster

In The Gene Therapy Plan, you’ll find chapters dedicated to diabetes and aging. And although they are discussed separately in the book, health conditions hardly ever exist in isolation. For one, diabetes has been linked to other conditions like obesity, heart disease, cancer, and advanced aging. Data show that memory and cognition may also be affected by diabetes and that the damage may contribute to the development of Alzheimer’s disease (AD).

Alzheimer’s disease is the most common form of dementia and it affects over 5 million Americans 65 years or older. The condition is often preceded by mild cognitive impairment (MCI). And as the disease progresses into Alzheimer’s, people with AD will experience increasing deterioration of their cognitive function and behavioral ability — to such a degree that it impairs their ability to carry out simple, everyday activities like getting dressed.

In an animal study published in The Journal of Clinical Investigation, researchers took a closer look at the link between diabetes and AD. The researchers induced a hyperglycemic state in young mice without beta-amyloid plaques (a proteinaceous plaque found in the brains of AD patients) and found that the plaque increased by 20 percent. When they repeated the experiment, this time using AD mice, the researchers found that the level of plaques doubled (40%).

Dr. Shannon Macauley, a postdoctoral research scholar and one of the lead authors in this study said, “Our results suggest that diabetes, or other conditions that make it hard to control blood sugar levels, can have harmful effects on brain function and exacerbate neurological conditions such as Alzheimer’s disease. The link we’ve discovered could lead us to future treatment targets that reduce these effects.”

While further studies targeting the pathways and mechanisms involved between diabetes and Alzheimer’s disease may take years of research, the good news is we don’t have to wait that long for answers. We can’t deny the deleterious effects that poor glucose control has on overall health. Eating too many simple carbs and sugars are no good for our health. And because our brains main source of energy comes in the form of glucose, the type of sugars we eat has a huge impact on brain health.

So to prevent and treat diabetes, we can take control of what we eat and engage in physical activity to maintain a healthy weight and regulate blood glucose levels. Eat organic, wholesome foods that are nutrient-rich not calorie-poor like chicory, probiotics, brown rice, and organic lean meats. Chicory, for example, contains vanadium, a mineral, that helps to promote insulin sensitivity.

By eating healthful foods that keep us feeling fuller longer and are chock-full of health-promoting nutrients, we ensure that we don’t experience blood sugar spikes that are often associated with processed carbohydrates and refined sugars.

Melatonin Supplements May Prevent Osteoporosis

shutterstock_270058169 adj

How many times have you heard this: “You’re getting older now, so you can’t do the same things you did in your twenties?” Getting older is often considered a disease, rather than a normal physiologic process in the body. Yes, it is true that the levels of hormones, enzymes, and other substances in the body decline with age, which lead to a host of health issues: poor vision, reduced hearing, forgetfulness, arthritis, and osteoporosis. 

However, every older adult is different, and how well one ages is determined in large part by nutrition, exercise, and sleep. While one octogenarian may use a walker to get around, another may be preparing for a marathon. The body is an amazing machine, but its longevity and health is determined by taking measures to prevent accelerated wear and tear by making healthy food choices, remaining physically fit, and getting adequate sleep. 

Sleep, in particular, is involved with the activation of certain chemicals like melatonin. Melatonin is a hormone that is released by a gland in the brain; the hormone plays an important role in regulating the circadian rhythm, which is the body’s internal 24-hour clock that controls the sleep-wake cycle. Melatonin is a light-induced hormone. So when it’s light, the body secretes less melatonin; when it’s dark, more melatonin. 

Melatonin’s release from the pineal gland is determined largely in part by the amount of light exposure — natural or artificial. So working late nights in a brightly lit environment or experiencing jet lag can disrupt normal melatonin levels. Even a simple task like drawing your curtains when it’s daytime may expose you to minimal light, which can also affect melatonin. Well, what does this have to do with aging? A lot. Because melatonin decreases with age, the lower amount contributes to sleep problems among older adults.

Various health problems such as osteoporosis ensue with inadequate shut-eye. Osteoporosis is the breakdown of bone that occurs most frequently as we age.  Certain bone cells are involved in building bone up and breaking it down, osteoblasts and osteoclasts, respectively. Interestingly, their activities also follow a circadian pattern: Osteoblasts are active in the daytime, but osteoclasts work at night. So if our sleep cycle is disrupted, as it tends to be in aging adults, then osteoclasts activity is revved up in sleepless states. With less sleep at night, osteoclasts accelerate the activity of bone breakdown, which leads to the porosity of bone commonly seen in osteoporosis. Weak and brittle bones place older adults at risk for fractures from falls. Statistics from the National Institute of Health (NIH) has indicated that approximately 34 million Americans have been diagnosed with osteoporosis.

Fortunately, physical activity, proper nutrition, and high-quality pharmaceutical supplements can help to protect many older adults from age-associated health problems like osteoporosis. In one animal study, researchers found that melatonin supplements helped to improve bone strength in old rats. The study used 22-month-old rats (the equivalent to a 60-year-old person) and divided the rodents into the melatonin-supplemented group and the placebo group. After 10 weeks, the researchers compared the two groups by evaluating the femur bones of the rats using various tests that measured bone strength and density. The researchers found that bone density and volume were greater in the melatonin-supplemented rats than the rats that didn’t receive the supplement.

This study provides great insight into how melatonin-regulated sleep cycle can improve bone health. The researchers plan to conduct further research to determine whether melatonin is preventing or reversing the effects of osteoclasts on bone. To prevent bone breakdown or to improve bone health, I suggest you give your bones a boost through physical activity such as walking briskly or tai chi, which also helps with balance.

In my new book, The Gene Therapy Plan, I recommend foods to promote healthy aging. Consume foods like milk, cheese, yogurt, almonds and green leafy vegetables because they contain loads of calcium that is good for building bones. Make getting adequate sleep a priority — restful nights help to maintain a good balance between daytime and nighttime melatonin. Some tips include not using bright lights a few hours before bedtime, don’t bring your cellphone, tablet, or laptop to bed with you, and lie down in your bed only when you’re feeling sleepy. These nutritional, workout, and sleep-promoting tips will help you to keep your circadian rhythm and bone health in check.

Low Levels of Vitamin D and Minerals Increase Insulin Resistance

Eggs Almonds Kale

 A study published in the Journal of Clinical Diagnostic Research compared the levels of vitamin D3, calcium, and magnesium in diabetic and nondiabetic patients. Researchers examined 30 diabetic patients and 30 matched controls. Glucose, insulin, and vitamin D3 levels were measured using fasting blood samples.1 Compared to vitamin D3 levels (19.55 ng/mL) found in healthy controls, levels (12.29 mg/mL) in the diabetic group were lower. In patients with diabetes, calcium and magnesium levels were low whereas fasting glucose and insulin levels and insulin resistance are high.

Higher insulin levels are expected in individuals with insulin resistance. When cells are insulin resistant, they become ineffective in transporting glucose molecules into cells. Because of this, there’s more glucose circulating in the blood. In the presence of elevated blood glucose, the beta cells of the pancreas work harder to release more insulin. Eventually, the pancreas becomes exhausted and is no longer able to pump out insulin.  Together, elevated blood glucose levels and ineffective pancreatic beta cells lead to type 2 diabetes. Circulating blood glucose levels are associated with many other chronic medical conditions like dementia, heart disease, obesity, and cancer.

Nutrients are required for various functions in cells. Calcium, magnesium, and vitamin D3 all play important roles in disease prevention and health. When it comes to type 2 diabetes, vitamin D, calcium, and magnesium have been associated with supporting glycemic control. The following table highlights the effects of these nutrients and their food sources:

Nutrient Effects on blood glucose control Dietary sources
Vitamin D Supports pancreatic beta cell activityBeta cells possess vitamin D receptors2Animal studies show that missing vitamin D receptors result in poor insulin secretion3 and vitamin D supplementation improves insulin secretion.4 The body’s main source of vitamin D is sunlight; however, with limited sunlight during the winter months in the northern hemisphere, dietary sources are needed to meet the daily requirement of vitamin D:

  • Fish—salmon, tuna, mackerel
  • Dairy—milk and cereal are fortified with vitamin D
  • Eggs
Calcium Insulin release requires calcium.5Patients with type 2 diabetes also have impaired intracellular calcium.6 Opt for soy milk and low-fat or fat-free yogurt and cheese.Many vegetables contain calcium: kale, broccoli, mustard greens, collards, cabbageEat nuts like almonds and Brazil nuts.
Magnesium People with type 2 diabetes tend to have low levels of  magnesium. Increasing magnesium levels protect against type 2 diabetes.7 Foods rich in magnesium include whole grains, nuts, and green leafy vegetables.

Refined sugars are a real threat to our health. Americans consume too much sugar, which leads to diseases like diabetes and heart disease. Chronic inflammation is associated with processed sugars that destroy healthy tissues and activates molecules in the body to promote disease. Poor diet, as well as lifestyle choices and environmental exposure, is linked to disease. And medications alone, simply, cannot change our health for the better. Medications mostly mask symptoms without addressing the underlying imbalances that cause disease. Eating foods that are nutrient-rich and contain bioactive molecules known to regulate glucose control is crucial to health and wellness. In my forthcoming book, The Gene Therapy Plan: Taking Control of Your Genetic Destiny with Diet and Lifestyle, I recommend foods that contain nutrients that balance glucose to prevent diabetes.

5 Things to Prevent Obesity

Fruits and Veges

Based on the USDA’s MyPlate initiative, the recommendation for a healthy diet is that people should consume about 2 to 3 cups of vegetables and 1.5 to 2 cups of fruits. One of the long-held views about eating plenty of fruits and vegetables is that it helps to also promote weight loss. Fruits and veggies contain loads of fibers that cannot be broken down by digestive chemicals in the gut. So that means these foods aren’t absorbed quickly and take a long time to travel through to the gut. And that’s a good thing — fiber in plant-based foods keeps people feeling fuller for a longer period of time.

But all the slicing, dicing, and chopping of fruits and veggies that will be either tossed in a salad or dropped in a juicer may have lots to offer as far as nutrition is concerned, but little to do with weight loss. One study showed that incorporating plenty of fruits and vegetables in your diet doesn’t help you shed those pounds.

Yes, fruits and vegetables will make you feel you sated longer.

Yes, by eating plant-based foods, you’re getting the benefits of loads of phytonutrients.

No, you’re not going to lose weight if you rely solely on fruit and vegetable intake.

Weight loss is a complex issue that is based on the amount of energy consumed as food and the amount of energy burned during exercise. To lose weight and keep it off you can’t rely on diet alone.  You have to combine a healthy diet and physical activity to help you maintain a healthy weight — not just as a short-term goal but for years to come. You can fight obesity, an epidemic in the United States, by doing the following:

  1. Drink a lot of water:  Organic juices are good, but our body, which is made up of over 70% water, needs plain old H2O for many of its cellular activities.
  2. Consume foods high in fiber: It lowers cholesterol and reduces the risk of diseases such as heart disease and diabetes.
  3. Avoid processed foods: To give foods a longer shelf life, foods are stripped of important nutrients and often too much salt and sugar are added back in order to enhance the taste.
  4. Steer clear of fizzy drinks: Sodas contain a lot of sugar and unhealthy additives.
  5. Engage in daily physical activity: Whether it’s walking the dog, running on a treadmill, or taking a yoga class, find an activity that you enjoy doing that will also help to keep your weight in check.

Good nutrition and physical activity help to promote a healthy lifestyle. While fruits and vegetables contain various components such as bioactive compounds, phytonutrients, and antioxidants, you also need to exercise to burn calories and keep a healthy weight. In my new book, The Gene Therapy Plan: Taking Control of Your Genetic Destiny with Diet and Lifestyle, which will be published by Viking in April, I explain how you can prevent and reverse conditions like obesity. I also offer plenty of nutritional recommendations and include recipes, so you can implement the Plan into your daily routine. Do this, and you’ll be well on your way toward achieving longevity and good health.

Bacterial Enzyme Overpowers Obesity and Conquers Cholesterol

Gut Bacteria

Obesity is a complex health problem. Many factors contribute to obesity: diet, genetics, and lifestyle choices. While there are no quick fixes to weight loss, gut bacteria do play significant roles in our health. Microbes in our gut help to regulate fat metabolism, maintain cholesterol levels, and block weight gain.

In fact, a study has shown that the gut microbial environment of obese individuals is different from those of lean people.  What’s even more interesting is that an obese person who loses weight has gut bacteria that resemble the bacteria found in a lean person.

Further studies in the area of gut bacteria have shown that these bugs produce an enzyme called bile salt hydrolase (BSH) that changes bile acid in the digestive tract. The modification of bile acid by BSH has been shown to improve fat metabolism. In one study, a group of researchers in Cork, Ireland examined lab mice and found that BSH significantly affects cholesterol and lipid metabolism to control obesity and prevent elevated cholesterol. High-level BSH expression in mice resulted in significant weight loss.

So what does all of this actually mean? While the exact mechanism of BSH activity is not clear, the enzyme’s influence on lipid regulation is apparent—BSH controls cholesterol and weight gain. To understand why the bacterial production of this enzyme is important to our health, you have to understand the function of bile acids.

Bile is made in the liver and stored in the gallbladder. It’s a fluid that comprises many molecules such as water, electrolytes, cholesterol, and, of course, bile acid. When we eat, the gallbladder contracts to release bile and the acid in bile is essential for the digestion and absorption of fats. As a result, bile acids are involved in maintaining an intricate balance in regulating fats in the body to prevent obesity and other metabolic conditions associated with excess fat storage (e.g., cardiovascular disease, diabetes).

The regulation of fats by bile acids is influenced by BSH, which is produced by bacteria in the gut. The study demonstrates the importance of gut microbiota in health. In particular, BSH production and its affect on regulating weight gain and cholesterol are strong indicators for obesity and cardiovascular disease. Bacteria in the gut compose 99% of the body’s genetic information, which is why it’s important to ensure healthy intestinal bacteria.

To maintain a healthy gut (1) stay hydrated by drinking lots of water, (2) eat foods that are high in fiber, and (3) consume foods like yogurt and kefir to boost good gut bacterial populations, and (4) add probiotic supplements to your diet. My latest book, The Gene Therapy Plan: Taking Control of Your Genetic Destiny Through Diet and Lifestyle, will be released in April from Viking and includes many healthful foods to beat obesity and rein in high cholesterol levels.

Curry Up Now: Indian Spice Enhances Colon Cancer Treatment


Cancer cases in the United States continue to grow—trailing closely behind heart disease, the No. 1 killer of Americans. Poor diet, no physical activity, and stress have all been linked to cancer. Cancer, however, is largely preventable through lifestyle choices.

Colorectal cancer is the second most common cause of cancer-related deaths among men and women in the U.S. Five percent of Americans will likely develop colon cancer in their lifetime. And early screening, especially in people who have a family history, helps to detect colon polyps before they become cancerous. Because of early detection and better treatments, over a million Americans have survived colorectal cancer. Unfortunately, cancer cells are strategic and can develop unique ways to avoid the effects of treatments. Cancer cells are abnormal cells that continue to grow with no plans of ever dying. These aggressive forms of cancer have defects that make them resistant to treatment.

If intestinal polyps are detected early, they can be surgically removed. When polyps aren’t caught in time, they develop into cancer. If colon cancer is detected at a later stage, chemotherapy and radiation therapy may be used alone or in combination to treat patients. Also, cancer stem cells (CSCs) can develop resistance, which renders conventional cancer treatments ineffective. That is why, in my practice, I integrate allopathic treatments and targeted-based nutrition to not only treat a patient’s symptoms but also the underlying cause of the medical problem.

The revolutionary science of epigenetics discusses the way in which environmental factors affect our genes to cause disease or promote health. Turmeric is a spice used to add flavor and yellow color to many Indian dishes. Often referred to as Indian saffron, it has been used to treat myriad health problems for thousands of years in Southeast Asia, such as arthritis, digestion problems, and parasitic infections.1 It’s also been shown to attack cancer cells.

A PLOS One study examined the effects of curcumin, an antioxidant compound in turmeric, on chemotherapy-resistant colon cancer cells.2 Researchers used two colorectal cell lines that were sensitive to 5-fluorouracil (5-FU), a chemotherapy drug. They also used 5-FU-resistant clones of these cell lines. One of the two sensitive cell lines and its corresponding resistant cell line were deficient in DNA mismatch repair (MMR).

Why is this deficiency relevant? Normal DNA uses MMR to recognize and repair genetic errors. Without MMR, damaged DNA can avoid replicative checkpoints and make it into future cell lines. This leads to genetic instability, cancer pathogenesis, and chemoresistant cancer cells.

Each cell line was exposed to different treatments: (1) 5-FU alone, (2) curcumin, and (3) pretreatment with curcumin followed by 5-FU. Although 5-FU worked in reducing the growth of sensitive colon cancer cell lines, curcumin reduced the proliferation of all cancer cell lines. And the combination therapy remarkably decreased cancer stem cells.

In my newest book, The Gene Therapy Plan: Taking Control of Your Genetic Destiny with Diet and Lifestyle, which will be published in April 2015 by Viking, I discuss the healthful benefits of turmeric and provide recipes for curry dishes. The spice is both chemopreventive and chemotherapeutic. If Indian food isn’t your thing, don’t worry. Foods such as salmon, blueberries, broccoli sprouts, and kale contain anti-inflammatory and antioxidant compounds that fight cancer.

A New Fat in Town: Omega-7

Sea Buckhorn

Fat Fights Metabolic Syndrome

If you’re constantly looking for ways to improve your diet, chances are you’ve already come across omega-3 fats. It’s a heart healthy fat that maintains normal growth and development and brain function. Since our bodies can’t produce omega-3s and we have to get it from our diet, it is called an essential fat.  Dietary sources, however, are limited to the fat of cold-water fish like salmon, tuna, and halibut. So some people may choose to take this fat as a supplement.

For good health, a balance between omega-3s and omega-6s (another essential fat) must be maintained. The stasis of omega fats is critical because omega-3s are anti-inflammatory, whereas omega-6s are proinflammatory. While the Mediterranean diet has a healthy ratio between these fats, the same can’t be said about the Western diet. Unfortunately, omega-6 fats are ubiquitous in our diet. Processed and refined foods promote an imbalance between these fats and trigger chronic inflammation and disease. In my new book, the Gene Therapy Plan, I explain how our diet affects our genes and health; in it you’ll learn what you can do to tip the scale to bring these fats toward a harmonious balance.

In the world of essential fats, omega-3s may take center stage. But a new player is drumming up some well-deserved attention—omega-7 fats. Omega-7 fats comprise fatty acids that are called palmitoleic acid, which is a monounsaturated fat (MUFA), not a polyunsaturated fat (PUFA) like omega-3 and -6. Compared to omega-3 fats, omega-7 fat exerts its health-promoting effect in a different way. Omega-3 fats become integrated with anti-inflammatory molecules to reduce active low-grade inflammation, which is a process linked to complex diseases.1,2 But omega-7 fats are lipokines, hormone-like substances, that regulates signals between distant tissues to optimize energy balance in the body.  In particular, palmitoleic acid controls the cell signals between muscle and fat tissues. This regulation helps to maintain energy use and storage by tissues in the body.

Diet plays a significant role in promoting inflammation, tissue damage, poor glucose control, and excess sugar storage—problems that are uniquely tied to metabolic syndrome. Metabolic syndrome is a condition characterized by five health issues:

  1. Poor sugar control
  2. Elevated cholesterol levels
  3. Hypertension
  4. Central obesity
  5. Chronic inflammation

Fortunately, omega-7 targets each of these five areas to prevent and treat metabolic syndrome. Omega-7 is a powerful anti-inflammatory molecule that reduces NF-kappaB, a major proinflammatory complex.3 The nutrient also improves glycemic control and cholesterol levels and controls weight. Omega-7 raises HDLs (good cholesterol) and lowers LDLs (bad cholesterol) and triglycerides.

Omega-7 is an amazing nutrient. It also works similarly to drugs that treat diabetes and high cholesterol, without the harmful side effects. Foods like macadamia nuts and sea buckthorn contain omega-7. These foods, unfortunately, contain high levels of palmitic acid. While palmitoleic acid is healthy, palmitic acid is not. A highly viscous oil, palmitic acid forms plaques that clogs arteries, which negates the health benefits of omega-7 fats in these foods.  Take omega-7 as a high-grade supplement to guard against metabolic syndrome and promote wellness. But before you take any supplement, consult with a health care professional.
